Well folks, the official Twitter app for the iPhone and iPod Touch has been released today and guess what’s called? It should be obvious. It’s called: Twitter (shocking I know). Now, Twitter isn’t a whole brand new app, it’s actually an updated version of Tweetie 2, which theoretically means this is Tweetie 3. Here’s the full list of changes in Twitter:

Search has been reorganized, now you can search all tweets and find users in the same spot, view Top Tweets and Browse Suggested users

Search results now include Top Tweets, try it with Trends…winner combo

You can now use Twitter without an account! Search, Browse uses, view trends and top tweets

Sign-up is now availabile within the application as well, complete with Suggested user list

More tab has been re-organized to accomplish all this. Users with one account can add a second account under the Accounts and Settings button here

Actions we’ve found people use most, like Retweet have been moved to the main actions bar

Minor tweaks were made to tweet rendering so they match Twitter.com tweets

Twitter is free and weighs in at 2.4 MB. Now, I’ve downloaded Twitter and gave it a test run to see how it compares to other Twitter apps. Well, Twitter is an okay Twitter client app for the iPhone and iPod Touch, however, I prefer Twitterriffic which comes in a free version and a paid version. The paid version only removes the ad in the free version, but I can live with an ad. There is also an iPad specific version of Twitterriffic which you can check out here. Here’s the features of Twitterriffic:

Another nice thing about Twitterriffic is that is has themes so you can customize your experience with the app. Anyway, both apps are free so just g0 ahead and download both apps and see which one you like the best! Here are the links to all the apps mentioned in this post:
